Non-woven bag production process
- Jul 11, 2018 -

Non-woven bags generally use screen printing technology, which is often referred to as "silk printing", which has been a common printing process for many manufacturers. Generally, it is artificially printed, so the color control on the process is not well controlled, so many new non-woven printing methods have emerged. Here we introduce several mainstream models on the market:

However, as the customer's printing quality and environmental protection requirements continue to increase, many new non-woven printing methods have emerged.

First, the watermark

It is named for its use of water-based elastic glue as a printing medium. It is more common in textile printing, also called printing. The color paste and the water-based elastic rubber are blended during printing. The printing plate can be washed directly with water without using a chemical solvent. It is characterized by good tinting strength, strong opacity and fastness, water wash resistance and basically no odor.

Second, gravure printing

The finished product processed in this way is usually called a laminated non-woven bag. The process is divided into two steps, that is, the conventional gravure printing process is used to print the image onto the film, and then the film with the pattern is laminated on the non-woven fabric by a film coating process. Generally, a large-area color pattern printed non-woven bag adopts this process. It is characterized by beautiful printing, full machine production, and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. The film is available in both bright and matt finishes, matte with a matte finish! The disadvantage is that it conflicts with the concept of environmental protection because the film is difficult to degrade.

Third, thermal transfer

Thermal transfer is a special printing in printing! The method requires an intermediate medium, that is, the graphic is printed onto the thermal transfer film or the thermal transfer paper, and then the pattern is transferred to the non-woven fabric by heating by a transfer device. The medium commonly used in textile printing is a thermal transfer film. The advantages are: beautiful printing, rich layered version, comparable to photos suitable for small-area color image printing. The disadvantages are high price and high printing cost.
